In 1917, Cartier launched TANK watch, the bracelet and case mix together like peas and carrots. Time for the card, and now this watch has become immortal. His stunning mature design and shapely appearance, convey luxury, refinement, and superb technology, but did not flow to blatantly artificial; as time goes by, watch the square looks increasingly perfected. With parallel lugs of the case, dial, crown, pointer, every detail is a continuation of the Cartier style, and establish a brand timing classic style.
